Abstract

La présente demande concerne un procédé et un dispositif de distribution de puissance. Le procédé comprend les étapes suivantes : un dispositif de commande reçoit des informations de capacité en provenance d'un dispositif radiofréquence, les informations de capacité étant utilisées pour indiquer la correspondance entre une amplitude de décélération de puissance d'un premier canal et une amplitude de réduction de puissance d'un deuxième canal; le dispositif de commande envoie des premières informations d'indication au dispositif radiofréquence, les premières informations d'indication étant utilisées pour indiquer que l'amplitude de décélération de puissance du premier canal est une première amplitude et utilisées pour indiquer que l'amplitude de réduction de puissance du deuxième canal est une deuxième amplitude, et la première amplitude et la deuxième amplitude étant déterminées en fonction des informations de capacité et d'une amplitude de décélération requise du premier canal, de telle sorte que la flexibilité de la distribution de puissance peut être améliorée.
